As root, edit the /etc/apt/sources.list and use copy and paste to replace all the contents of the file so it looks just like the list shown below. Note that the sign "#", as in front of the top directions below, serves to comment out a line of code so it is not read.

Step 2: Edit your Apt Preferences

As root, edit the /etc/apt/preferences file and add the three lines in red bold below. Do not make any other changes to any other lines in that file.

Detailed step-by step instructions how to do this are:

<alt> + <F2> - to start krunner

kdesu kwrite /etc/apt/preferences - put this in the dialogue box and hit enter

Step 3: Reload Synaptic

To effect changes made in Steps 1 and 2, open Synaptic and hit the Reload button.

Step 4: Read these notes

By following the above steps, the Testing Repositories are disabled for safety. Before you enable them, please see the notes at the Community Repository page.

The debian-multimedia repository is also disabled for safety because the Community Repository has many of the correct packages needed for your system to work as intended. If you do need some packages from the debian-multimedia repository that are not in the Community Repository (for example libdvdcss2 or Abobe Acrobat Reader) is to OK install them by temporarily using the debian-multimedia repository by following these steps:

Use Synaptic to install only the software you need -- but do not "Mark All Upgrades" or otherwise upgrade any other packages as the ones from debian-multimedia may conflict with the packages used by the Community Repository.
